With a blend of 6500 K white, 450 nm blue, and 660 nm red LEDs, this fixture creates a vibrant, visually rich environment. The light’s color rendering (CRI 90) and its measured Lux (around 4000) and PAR (82) work together to produce a bright yet balanced illumination that makes greens, corals, and fish tones pop without glare.\u003c\/p\u003e\n\n\u003ch3\u003eFlexible Day \u0026amp; Night Cycling\u003c\/h3\u003e\n\u003cp\u003eTwo lighting modes keep your tank looking lively while offering a natural rhythm for its inhabitants.

In addition, the light can emulate gentle sunrises and sunsets to help create a familiar daily rhythm without stressing the ecosystem.\u003c\/p\u003e\n\n\u003ch3\u003ePrecise Brightness Control\u003c\/h3\u003e\n\u003cp\u003eThe fixture provides six brightness levels to suit different times of day and viewing preferences.
